I checked internally and the method may be safely deleted. And then I believe you can use NestedSet for providedProtoSources.

Keep. Can't be safely removed.

Why do you need to flatten the NestedSet? If I understand this correctly, so that you can use overloaded ProtoLangToolchainProvider.create? I'd prefer if you remove the old implementation of create and just use NestedSet. I checked that there are no dependencies internally. If you're worried about other forks of Bazel, perhaps you could change the create method name?

No, this not for overloading ProtoLangToolchainProvider#create(). Today, every <lang>_proto_library has to flatten the set to figure out which of its srcs is in blacklistedProtos(), which does have performance overhead. We can avoid that by flattening it here once and propagate the excluded protos as list instead. We trade some (finite) memory for performance.
The information is already part of another field. Cleanup after bazelbuild#12431 and bazelbuild#10939
